NASA/CR-1998-207400, NASA CONTRACTOR REPORT: ELECTRICAL BONDING: A SURVEY OF REQUIREMENTS, METHODS, AND SPECIFICATIONS (MAR-1998)., This document attempts to explain the various types of electrical bonding requirements and to provide the basic requirement for each type where possible. In some cases the specific values of bonding resistance and impedance may vary depending upon other requirements on the program. In these cases the type of data required to determine the specific values is defined. There are several reasons for requiring good electrical conductivity between equipment and structure and between various parts of structure. Improved electrical bonding with reduced effort can result from understanding the different types of bonding requirements and the reasons for each. Good electrical bonding on a spacecraft is often not completely verifiable. In some cases electrical bonding specifications state requirements that are compromises so they can be verified by measurement. These compromised requirements are often met by methods that may not provide a good bond under certain circumstances.
